New KOSBO.COM site is up now. Simple, light design for easy browsing and buying clocks.

You can, but don't have to register on site : just find the clock, buy it and pay via Paypal. That's it!

Please note, this site is under construction,  all products/docs are listed now,  but you may find broken links yet...


Time is flying!

In October 2005 I have released and sold my first Sparkletube, so era has begun.

KOSBO.COM is 10 years old now. Happy birthday to us! ;-)

It was really exciting time, thanks a lot to all my Customers, who likes and buys my clocks. Special thanks to my family and friends, who supports me all the time.
I've met lots of interesting people, designed and manufactured 19 Nixie and VFD clocks, which does not count my first great device called Sparkletube.
Several special edition clocks were released too, which includes clocks to TomorrowLand movie, UK BBC sport documentary and a few more.

More clocks will be released during this autumn and it's time to refresh my web site too!

Best wishes, Konstantin



Still nice time to fly quadrocopter - new modern hobby.

I like it and do it quite often. I am sure, some of you would like to do so too,
have a look at this nice web site to start to build your own good quality quadrocopter
or to replace your quadrocopter frame to really good, well designed one:

All the best, Konstantin
